Definitions
- the present invention relates to the field of components of a power system, and in particular, to a shell structure for a thyristor trigger unit.
- thyristor trigger units for the converter valve may be installed in the following manner: A main trigger circuit board is packaged in a shell, and then, the shell is screw-fixed on a radiator at a valve layer. A detachable panel of the trigger unit is located at a bottom part of the shell, and the main circuit board is fixed on an inner side face of the shell.
- the thyristor trigger unit used in an ice-melting project is also of a flat cuboid structure. It comprises a bottom retaining plate and an upper housing. A main circuit board is installed on the rectangular retaining plate, and the cuboid upper housing covers the main circuit board. Several holes are formed on the upper housing for passage of optical fibers and cables. The trigger unit is fixed via a small portion extending from the bottom retaining plate.
- Such a shell structure of the thyristor trigger unit facilitates installation and fixation of the circuit board inside the shell, but has some disadvantages:
- the bottom retaining plate is relatively broad, and the extension is also relatively broad, a large installation and fixing space is required, and the shell is not applicable when a relatively narrow radiator is used in a relatively compact valve.
- optical fibers and cables go through the holes on the upper housing, when the upper housing needs to be removed during commissioning of the thyristor trigger unit, the optical fibers and the cables need to be disconnected as well, and as a result need to be reconnected after the commissioning, bringing about great troubles to the commissioning.
- An objective of the present invention is to provide a shell structure for a thyristor trigger unit that has a simple structure, requires a small installation and fixing space, facilitates commissioning, and has a strong anti-interference capability.
- a shell structure for a thyristor trigger unit includes a shell body and a side plate, where
- At least one screw hole used to fix a trigger circuit board on the rear panel is disposed on the rear panel.
- At least one weep hole used to discharge water that accidentally enters a thyristor trigger unit in time is formed on the lower panel.
- At least one power cable hole for passing of power cables is formed on the lower panel.
- a main circuit board is connected to a main circuit at a valve layer via several cables extending out of the power cable holes for the purpose of receiving power.
- a thyristor trigger line hole for passing of a thyristor trigger line is formed on the left panel.
- the thyristor trigger unit sends a trigger electrical impulse to a thyristor gate via a trigger line extending out of the thyristor trigger line hole.
- two optical fiber holes for passing of one trigger optical fiber and one feedback optical fiber are formed on the right panel. Each of the two optical fiber holes corresponds respectively to one feedback optical fiber interface and one trigger optical fiber interface.
- At least one fixing rod is disposed inside the cuboid, one end of the at least one fixing rod is a threaded rod, the other end has an internal screw hole, and the threaded rod is mated with a screw hole on the rear panel.
- At least one installation screw hole is formed on the side plate, and the side plate is fixed on the open face via at least one screw, the at least one installation screw hole, and the at least one fixing rod.
- At least one fixing screw hole used to fix the shell body on a radiator at a valve layer is formed on the square retaining plate.
- the present invention has the following beneficial effects: 1. the fixation of a shell and the installation of a circuit board are facilitated; 2. signal measurement and commissioning in a circuit board is facilitated; 3. drainage in the case of water leakage inside a valve is facilitated.
- FIG. 1 is a schematic 45-degree view of a shell structure for a thyristor trigger unit
- FIG. 2 is a side view of a thyristor trigger unit.
- a shell structure for a thyristor trigger unit includes a shell body and a side plate 2 .
- the shell body is integrally-formed which comprises a holder and a cuboid structure.
- the cuboid structure is a cuboid having an opening at the front.
- the cuboid includes a rear panel 7 , a left panel 11 , a right panel 12 , an upper panel 1 , and a lower panel 5 .
- An open face is formed at the front opening of the cuboid.
- the holder includes a square retaining plate 3 and two triangular stiffener plates 4 .
- the square retaining plate 3 is formed by the lower panel 5 extending towards a side of the left panel 11 in a long side direction of the cuboid.
- the triangular stiffener plates 4 are fixedly connected between the square retaining plate 3 and the left panel 11 .
- the side plate 2 is mated with and detachably mounted on the open face to seal off the open face and form a closed six-face cuboid structure.
- At least one screw hole 16 used for fixing a trigger circuit board 15 on the rear panel 7 , is disposed on the rear panel 7 .
- At least one weep hole 9 used for discharging water that accidentally enters the thyristor trigger unit in time, is formed on the lower panel 5 .
